The $_{\\Lambda}^{3}\\mathrm{H}$ has been reconstructed via its two-charged-body decay channel, i.e., $_{\\Lambda}^{3}\\mathrm{H} \\rightarrow {}^{3}\\mathrm{He} + \\pi^{-}$. A Blast-Wave model fit of the $p_{\\rm T}$-differential spectra of all nuclear species measured by the ALICE collaboration suggests that the $_{\\Lambda}^{3}\\mathrm{H}$ kinetic freeze-out surface is consistent with that of other nuclei. The ratio between the integrated yields of $_{\\Lambda}^{3}\\mathrm{H}$ and $^3\\mathrm{He}$ is compared to predictions from the statistical hadronisation model and the coalescence model, with the latter being favoured by the presented measurements.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.155083.v1/t1","@type":"Dataset","description":"Transverse momentum distributions of (anti)hypertriton in 0-10% V0M centrality class","name":"(Anti)hypertriton spectrum in 0-10% V0M centrality class"},{"@id":"https://doi.org/10.17182/hepdata.155083.v1/t2","@type":"Dataset","description":"Transverse momentum distributions of (anti)hypertriton in 10-30% V0M centrality class","name":"(Anti)hypertriton spectrum in 10-30% V0M centrality class"},{"@id":"https://doi.org/10.17182/hepdata.155083.v1/t3","@type":"Dataset","description":"Transverse momentum distributions of (anti)hypertriton in 30-50% V0M centrality class","name":"(Anti)hypertriton spectrum in 30-50% V0M centrality class"},{"@id":"https://doi.org/10.17182/hepdata.155083.v1/t4","@type":"Dataset","description":"Integrated (${}_{\\Lambda}^{3}\\mathrm{H} + {}^3_ {\\overline{\\Lambda}}\\overline{\\mathrm{H}}$)/2 yields in different V0M centrality classes","name":"Hypertriton production yield"},{"@id":"https://doi.org/10.17182/hepdata.155083.v1/t5","@type":"Dataset","description":"Hypertriton over He3 ratio as a function of multiplicity","name":"Hypertriton over He3 ratio as a function of multiplicity"},{"@id":"https://doi.org/10.17182/hepdata.155083.v1/t6","@type":"Dataset","description":"Hypertriton over He3 ratio as a function of $p_{T}$ in 0-10% V0M centrality class","name":"Hypertriton over He3 ratio as a function of pT in 0-10%"},{"@id":"https://doi.org/10.17182/hepdata.155083.v1/t7","@type":"Dataset","description":"Hypertriton over He3 ratio as a function of $p_{T}$ in 10-30% V0M centrality class","name":"Hypertriton over He3 ratio as a function of pT in 10-30%"},{"@id":"https://doi.org/10.17182/hepdata.155083.v1/t8","@type":"Dataset","description":"Hypertriton over He3 ratio as a function of $p_{T}$ in 30-50% V0M centrality class","name":"Hypertriton over He3 ratio as a function of pT in 30-50%"}],"identifier":[{"@type":"PropertyValue","propertyID":"HEPDataRecord","value":"https://www.hepdata.net/record/ins2791616?version=1"},{"@type":"PropertyValue","propertyID":"HEPDataRecordAlt","value":"https://www.hepdata.net/record/155083"}],"inLanguage":"en","name":"Measurement of ${}_{\\Lambda}^{3}\\mathrm{H}$ production in Pb-Pb collisions at $\\sqrt{s_{\\mathrm{NN}}}$ = 5.02 TeV","provider":{"@type":"Organization","name":"HEPData"},"publisher":{"@type":"Organization","name":"HEPData"},"url":"https://www.hepdata.net/record/ins2791616?version=1","version":1}
